Die Funktion des beschriebenen Gerätes ist folgende:The function of the device described is as follows:

Es sei angenommen, die Flüssigkeitsvorratskammer 2 sei mit Flüssigkeit gefüllt und die im Inneren des Balls 40 ausgebildete Pumpkammer 54 sei noch nicht mit Flüssigkeit gefüllt.It is assumed that the liquid storage chamber 2 is filled with liquid and that in the Pump chamber 54 formed inside ball 40 is not yet filled with liquid.

Durch Eindrücken des Betätigungselements 44 vermindert sich das Volumen der Pumpkammer 54 bzw. erhöht sich der Druck in der Pumpkammer, wodurch das Rückschlagventil 29 öffnet. Wenn das Betätigungselement 44 anschließend losgelassen wird, nimmt der Ball 40 sein ursprüngliches Volumen wieder ein, wodurch in der Pumpkammer 54 ein Unterdruck entsteht, der das Rückschlagventil 29 schließt und das Rückschlagventil 21, öffnet. Dadurch wird Flüssigkeit aus der Vorratskammer 52 in die Pumpkammer 54 angesaugt. Der Vorgang wird mehrere Male wiederholt, wobei sich die Pumpkammer 54 mit Flüssigkeit füllt. Diese Füllung ist luftfrei, wenn das Gerät bei diesem Füllvorgang mit dem Auftragselement 30 nach oben gehalten wird. Wird bei mit Flüssigkeit gefüllter Pumpkammer 54 das Betätigungselement 44 gedrückt, so wird Flüssigkeit durch das offene Rückschlagventil 29 in das Auftragselement 30 hineingedrückt, so daß mit dem Auftragselement 30 Flüssigkeit auf einer Unterlage aufgebracht werden kann.Pressing the actuating element 44 reduces the volume of the pump chamber 54 or increases the pressure in the pump chamber, causing the check valve 29 opens. If the actuator 44 is then released, the Ball 40 re-enters its original volume, thereby entering pump chamber 54 Vacuum arises, which closes the check valve 29 and the check valve 21, opens. This draws liquid from the storage chamber 52 into the pumping chamber 54. The process is repeated several times, with the pumping chamber 54 moving with it Fills liquid. This filling is air-free if the device is used during this filling process the order element 30 is held upwards. Will be when filled with liquid Pump chamber 54 pressed the actuator 44, so liquid is through the open Check valve 29 pressed into the application element 30, so that with the application element 30 liquid can be applied to a base.

Fig. 2 zeigt eine gegenüber Fig. 1 abgeänderte Ausführungsform des Gerätes.FIG. 2 shows an embodiment of the device modified compared to FIG. 1.

Die Pumpkammer 54 ist bei dieser Ausführungsform unmittelbar durch das Gehäuse 2 und dessen Trennwände 4 und 6 gebildet. Das Betätigungselement 44 ragt in einen Balg 56 ein, der dichtend mit der Innenseite des Gehäuses 2 verbunden ist und zwischen dem und der gegenüberliegenden Innenseite des Gehäuses 2 sich eine Feder 58 abstützt. Ähnlich wie bei der Ausführungsform gemäß Fig. 1 ist auf diese Weise das Innere der Pumpkammer gegenüber dem Betätigungselement ohne Spalten oder bewegliche Führungen abgedichtet. Die Funktion entspricht der des Gerätes gemäß Fig. 1. Beim Eindrücken des Betätigungselements 44 vergrößert sich der Balg 56 und drück Flüssigkeit aus der Pumpkammer 54 in das Auftragselement. Beim Loslassen bewegt sich unter der Kraft der Feder 58 der Balg 56 zusammen mit dem Betätigungselement 44 zurück, bis ein nicht bezifferter Band das Betätigungselement 44 in Anlage an die Innenseite des Gehäuses 2 kommt. Dabei wird Flüssigkeit aus der Vorratskammer 52 in die Pumpkammer 54 gesaugt.The pump chamber 54 is in this embodiment directly through the housing 2 and the partitions 4 and 6 formed. The actuating element 44 projects into a bellows 56, which is sealingly connected to the inside of the housing 2 and between the and the opposite spring of the housing 2 a spring 58 is supported. Similar to 1 is in this way the interior of the pump chamber opposite sealed the actuator with no gaps or movable guides. The Function corresponds to that of the device according to FIG. 1. When the actuating element is pressed in 44 the bellows 56 increases and pushes liquid out of the pump chamber 54 the order element. When released, the bellows moves under the force of spring 58 56 back together with the actuating element 44 until a band that is not numbered Actuator 44 comes into contact with the inside of the housing 2. Doing so Liquid is sucked from the storage chamber 52 into the pumping chamber 54.

Die Durchgangsöffnungen enden mit einer oder mehreren seitlichen Öffnungen 78 bzw. 80. Jeder Ansatz 70 bzw. 72 wird dichtend von einer Öffnung eines in seinem Inneren eine Pumpkammer 82 bildenden ballartigen Bauteils 84 aus elastisch nachgiebigem Werkstoff umschlossen, wobei die mit den Öffnungen zur Befestigung an den Ansätzen 70 bzw. 72 ausgebildeten Bereiche des ballartigen Bauteils 84 mit segelartigen bzw. Lippen 86 bzw. 88 ausgebildet sind. Bei rotationssymmetrischer Ausbildung kann jeweils eine umlaufende Lippe 86 bzw. 88 vorhanden sein. Die Lippe 86 ist derart ausgebildet, daß sie sich in Ruhelage vom Verlängerungsbereich des Bauteils 84 zu dessen Befestigung vom Ansatz 70 aus über die seitliche Öffnung 78 erstreckt und am inneren Endbereich des Ansatzes 70 anliegt. Die Lippe 88 ist derart ausgebildet, daß sie sich vom Inneren des ballförmigen Bauteils 84 bezogen auf die Pumpkammer 82 innerhalb der seitlichen Öffnung 80 an das vordere Ende des Ansatzes 72 anlegt. Es können jeweils eine oder mehrere Öffnungen 86 bzw. 88 vorgesehen sein. Die Lippen 86, 88 bilden zusammen mit den Öffnungen 78, 80 gegensinnig wirkende Rückschlagventile 87 und 89. The housing 62 is here in the form of a cylinder closed on one side with a ventilation opening 64 trained through the floor. The partitions 66 and 68 are in one piece formed and have approaches 70 and 72 to be pointed towards each other, with through openings 74 and 76 are provided. The through openings end with one or more lateral openings 78 and 80. Each extension 70 and 72 is sealed by one Opening of a ball-like component 84 forming a pump chamber 82 in its interior made of resilient material, with the openings for fastening regions of the ball-like component 84 formed on the projections 70 and 72 are formed with sail-like or lips 86 or 88. With rotationally symmetrical training there can be a circumferential lip 86 and 88, respectively. The lip is 86 formed in such a way that in the rest position they extend from the extension area of the component 84 its attachment extends from the shoulder 70 over the side opening 78 and on the inside End area of the approach 70 is present. The lip 88 is designed such that it is from the inside of the ball-shaped component 84 with respect to the pump chamber 82 within the creates lateral opening 80 at the front end of the neck 72. There can be one or more openings 86 and 88 may be provided. The lips 86, 88 form together with the openings 78, 80 counter-acting check valves 87 and 89.

In der Trennwand 78, die ein vorderes Abschlußteil des Gehäuses 62 bildet, ist ein Auftragselement 90, im dargestellten Beispiel ein Pinsel, aufgenommen. Zum Schutz des Auftragselements, auch vor einem Austrocknen, ist eine abnehmbare Kappe 92 vorgesehen. Seitlich neben dem bauförmigen Bauteil 84 ist, wie bei der Ausführungsform gemäß Fig. 1, ein Betätigungselement 44 im Gehäuse 62 verschiebbar angeordnet.In the partition 78, which forms a front end part of the housing 62, there is an application element 90, in the example shown a brush. To protect the order element, even before drying out, a removable cap 92 is provided. Laterally next to the structural component 84, as in the embodiment according to FIG. 1, an actuating element 44 is arranged displaceably in the housing 62.

Die Trennwand 66 weist einen Ringflansch 94 auf, auf dem ein sackartiger Behälter 96 geknüpft ist, der eine Flüssigkeitsvorratskammer 52 bildet.The partition 66 has an annular flange 94 on which a sack-like container 96 is knotted which forms a liquid storage chamber 52.

Die Funktion des Gerätes gemäß Fig. 3 entspicht der der Fig. 1. Die Segel 86 wirken wie Rückschlagklappen, die bei Überdruck in der Pumpkammer 82 schließen und verhindern, daß Flüssigkeit aus der Pumpkammer 82 in die Flüssigkeitsvorratskammer 52 zurückströmt. Die Segel 88 wirken wie Rückschlagklappen, die bei Unterdruck in der Pumpkammer 82 schließen und verhindern, daß Luft oder Restflüssigkeit aus der Durchgangsöffnung 76 in die Pumpkammer 82 gelangt.The function of the device according to FIG. 3 corresponds to that of FIG. 1. The sails 86 act like Non-return valves which close and prevent in the event of overpressure in the pump chamber 82, that liquid flows back from the pump chamber 82 into the liquid storage chamber 52. The sails 88 act as non-return flaps which are in the pump chamber when there is negative pressure 82 close and prevent air or residual liquid from the through opening 76 reaches the pump chamber 82.

Fig. 4 zeigt. wie das in Fig. 1 bis 3 dargestellte, insgesamt mit 100 bezeichnete Gerät vorteilhafterweise in einer Hand gehalten wird. Wie ersichtlich, kann das Gerät 100 derart gehalten werden, daß der Daumen einer Hand auf das Betätigungselement 44 drückt, wobei die Menge an Flüssigkeit, die aus dem Auftragselement abgegeben wird, bequem durch die Bewegung bzw. durch den Druck des Daumens auf das Betätigungselement 44 gesteuert werden kann. Es versteht sich, daß das Gerät 100 auch derart gehalten werden kann, daß einer der Finger, beispielsweise der Zeigefinger, auf das Bedienungselement 44 drückt.Fig. 4 shows. like the device shown in FIGS. 1 to 3, designated 100 in total is advantageously held in one hand. As can be seen, device 100 can do this are held so that the thumb of one hand presses on the actuating element 44, the amount of liquid dispensed from the applicator element being convenient by the movement or pressure of the thumb on the actuating element 44 can be controlled. It goes without saying that the device 100 can also be held in this way can that one of the fingers, for example the index finger, on the operating element 44 suppressed.

Vorteilhaft ist, das Auftragselement nicht rotationssymmetrisch auszubilden, sondern in einer Form, in der die Abmessung des Auftragselements in einer Richtung senkrecht zur Betätigungsrichtung des Betätigungselements 44 größer ist als parallel dazu. Damit läßt sich eine Unterlage bequem wohl definiert mit Flüssigkeit beschichten. It is advantageous not to make the application element rotationally symmetrical, but in one Shape in which the dimension of the application element in a direction perpendicular to the direction of actuation of the actuating element 44 is larger than parallel to it. So that can coat a base with liquid in a well-defined manner.

Fig. 5 zeigt eine Ausführungsform eines Auftragselements 30, wie es beispielsweise in Fig. 1 dargestellt ist. Dargestellt sind zwei zueinander senkrechte Längsschnitte, parallel bzw. senkrecht zu den Schlitzen 32. Vorteilhafterweise ist die Schlitzlängsrichtung parallel zur Bedienungsrichtung des Betätigungselements 44 und endet das Auftragselement 30, das beispielsweise aus Gummi bestehen kann, in einer konvexen Fläche, die zwischen den Schlitzen 32 vorsteht. Das Auftragselement gemäß Fig. 5a und 5b eignet sich besonders gut beispielsweise zum Auftragen von flüssigen Klebern.FIG. 5 shows an embodiment of an application element 30, as is shown for example in FIG Fig. 1 is shown. Two longitudinal sections perpendicular to each other are shown, parallel or perpendicular to the slots 32. The longitudinal slot direction is advantageously parallel to the operating direction of the actuating element 44 and the order element 30 ends For example, made of rubber, in a convex area between the Slits 32 protrudes. The application element according to FIGS. 5a and 5b is particularly suitable good for applying liquid glue, for example.

Das Auftragselement gemäß Fig. 5c ist ein Flachpinsel, der in einer Richtung parallel zur Betätigungsrichtung des Betätigungselements größer ist als senkrecht dazu.5c is a flat brush that is parallel to one direction Actuating direction of the actuating element is greater than perpendicular to it.

Ein Vorteil der beschriebenen Geräte liegt darin, daß die Flüssigkeit bzw. das fließfähige, aufzutragende Medium an keiner Stelle mit irgendeiner beweglichen Dichtung in Berührung kommt, so daß Undichtigkeiten oder die Berührung mit Luft ausgeschlossen sind.One advantage of the devices described is that the liquid or the flowable medium to be applied never touches any movable seal comes, so that leaks or contact with air are excluded.

Die beschriebenen Geräte können in vielfältiger Weise abgeändert sein. So muß das Gehäuse nicht zwangsläufig zylindrisch sein. Je nach Einsatzzweck und Handhabung sollte es eine ergonomisch günstige Form haben. Das Betätigungselement 44 kann auch durch ein Bauteil gebildet sein, das beim Aufsetzen des Gerätes auf einer Unterlage gegen den Ball 40 bzw. das bauförmige Bauteil 84 gedrückt wird. Damit nicht die gesamte Kraft des Betätigungselements 44 auf die Pumpkammer wirkt, kann zur elastischen Vorspannung des Betätigungselements 44 eine zusätzliche Feder vorgesehen sein. Für das Auftragselement gibt es unterschiedliche, am jeweiligen Verwendungszweck ausgebildete Konstruktionen. Beispielsweise kann es als feinhaariger kleiner Pinsel ausgebildet sein, wie er als Lackstift eingesetzt wird. Andere Ausführungsformen eignen sich zum Aufbringen von Lippenstift oder Nagellack usw..The devices described can be modified in many ways. So the housing must not necessarily be cylindrical. Depending on the intended use and handling, it should have an ergonomically favorable shape. The actuator 44 can also by a Component be formed when the device is placed on a surface against the ball 40 or the structural component 84 is pressed. So that not the entire force of the actuator 44 acts on the pump chamber, can be used for elastic prestressing of the actuating element 44 an additional spring can be provided. For the order item there there are different constructions designed for the respective purpose. For example it can be designed as a fine-haired small brush, such as a paint pen is used. Other embodiments are suitable for applying lipstick or nail polish etc.
